AWE Tuning has merged over two decades in supercar performance products with rigorous study of the peerless engineering behind the McLaren MP4-12C to create one of the finest exhaust systems available, for one of the finest vehicles available.

AWE Tuning McLaren MP4-12C Performance Catalysts

The AWE Tuning MP4-12C Performance Catalysts are aggressive, unbridled and unique.

Verified to fit both the 12C Coupe and the 12C Spider, the AWE Tuning MP4-12C Performance Catalysts are the first in the world to feature a 200 cell hi-flow catalyst solution.

About the 200 cell HJS HD Catalysts

Due to its dimensions, standard 300 cell HJS catalysts would have been far easier to fit into the McLaren. However, there is no HD (High Durability) spec 300 cell HJS catalyst, and the close engine placement and power output that these catalysts are subject to in the MP4-12C, in our analysis, mandated better. The 200 cell HJS HD catalyst, while significantly more complex to integrate, afforded not only the durability we desired, but the added benefit of significant increased flow over a 300 cell count. In summary, we chose to not settle, because the MP4-12C deserves it.

Peerless build quality

AWE Tuning precision engineering and fixture development permits the factory heat shields to re-attach completely intact, with no deformation or subpar installation results. Further, our integration of proper articulating stainless steel fully lined flex joints provide proper torsional relief between the engine and the fixed muffler mounting points.

Besides factory correct fitment and long term durability, all this engineering adds up to an impressive +46hp and +61tq, as measured on the AWE Tuning in-house Mustang chassis dyno.

Please note, the AWE Tuning Performance Catalysts are for racing use only.

AWE Tuning McLaren MP4-12C Performance Exhaust

The AWE Tuning McLaren MP4-12C Performance Exhaust is designed to perfectly smooth the aggressively raw tone that results from mating the AWE Tuning Performance Catalysts to the stock exhaust system. The resulting acoustic character is nothing short of breathtaking, offering a note that is both hard-hitting and exotic.

The exhaust is constructed from mandrel bent 304 stainless steel at 3” diameter throughout and features a small balance opening between the banks which produces the exotic, high pitched wail. The AWE Tuning Performance Exhaust features logo tips evoking the factory geometry in a discrete satin black finish, or an optional high profile bare stainless steel machined finish.
